[PVE-User] Ceph - PG expected clone missing

[Karsten Becker]

Hi,

I have one damaged PG in my Ceph cluster. All OSDs are BlueStore. How do I
fix this?

"ceph pg repair 10.7b9" fails and is not able to fix ist. A manually
started scrub "ceph pg scrub 10.7b9" also.

size=3 min_size=2... if it's of interest.

Any help appreciated.
